So for a while now my Samsung Plasma has had a permanent pink smudge that's in the image (kind of like a paint brushing effect), and you can see it all over the screen on a white background. But when there is a scene with colour it's not really as visible but still there. I've done a quick search online and I've seen other people complain about the issue and some call it pink banding and one claimed a technician changed the voltage on the TV which fixed the issue, but I want to know if it's worth fixing (an estimation on how much it'd cost?), and what exactly causes this issue?
I found this picture on the internet and it looks exactly like this but a lot worse, is anyone familiar with this?:
